Answer:
a. 10.0 g
Explanation:
The molar mass of NaOH is 39.997 grams which was calculated by adding the molar mass of Sodium, Oxygen, and Hydrogen 
. But before we do anything with this number we must first convert 
molecules to moles. We can do this by dividing by Avogadro's number or 
( 
moles). We then convert moles to grams by multiplying by the molar mass of NaOH, (
grams). This is almost exactly 10 and the margin of error is likely due to the original numbers not being precise enough.
Answer:
The phenomenon of plasmolysis.
Explanation:
When cells of Elodea are placed in a salt solution the phenomenon of plasmolysis occurs and the water will start to move out from the cell. The concentration of salts in the cell will get high due to the diffusion of salt molecules inward. The organelles will look like as they are centered to the cell by hook.
Answer:
I will say D. The molecules become arranged into regular cubic arrangement. but i'm not 100% sure
Explanation:
Answer:
Explanation:
Assumptions
- They would ionize completely, or you must assume that.
- The volumes must be the same as well.
- 0.11M Cu(NO3)2 ===> 0.11MCu2+ + 0.22 NO3-
Note
The concentrations would merely add. All things change if the assumptions I've made are not true.
